Abstract:
A conjugated tetracarboxylate, 1,2,4,5-benzenetetracarboxylate sodium salt (Na4C10H2O8), was designed and synthesized as an anode material in Na-ion batteries (NIBs). This organic compound shows low redox potentials (∼0.65 V), long cycle life (1000 cycles), and fast charging capability (up to 2 A g-1), demonstrating a promising organic anode for stable and sustainable NIBs.

Ionic Bonding and Electron Transfer
Ionic Bonds
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.

Voltaic/Galvanic Cells
Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
